Thread status and its conversion

The thread object uses the ThreadState property to indicate the thread status.

ThreadState is an enumeration type object with the flag feature. Therefore, bitmask must be used to determine the current state of the thread. as a special case, because the bit code of the Running state is 0, determine whether the thread is running in the following way: (myThread. threadState & (ThreadState. stopped | ThreadState. unstarted) = 0.

The enumerated members are as follows:

 

	Member name	Description
	Running	The thread has been started, it is not blocked, and there is no pendingThreadAbortException.
	StopRequested	The thread is being requested to stop. This is for internal use only.
	SuspendRequested	The thread is being requested to suspend.
	Background	The thread is being executed as a background thread, as opposed to a foreground thread. This state is controlled by setting theThread. IsBackground property.
	Unstarted	The Thread. Start method has not been invoked on the thread.
	Stopped	The thread has stopped.
	WaitSleepJoin	The thread is blocked. this cocould be the result of calling Thread. sleep orThread. join, of requesting a lock-for example, by callingMonitor. enter orMonitor. wait-or of waiting on a thread synchronization object such asManualResetEvent.
	Sushortded	The thread has been suincluded.
	AbortRequested	The Thread. Abort method has been invoked on the thread, but the thread has not yet initialized ed the pendingSystem. Threading. ThreadAbortException that will attempt to terminate it.
	Aborted	The thread state already des AbortRequested and the thread is now dead, but its state has not yet changed toStopped.

 

The status transition diagram is as follows:
